If I recall correctly I paid around $60 in parts to Digikey to replace the caps in three DSP5000s (two towers and a center).

Also included was the resistors which are most likely burnt up by now.
This did not including new tweeters, but you may not need those.

The soldering is pretty easy, all leaded parts (no surface mount). The resistors can sometimes be a pain because the heat may have damaged the traces on the board. White wire is your friend here.
If you decide to go for it I can walk you through the process.

Mine were 24/96 versions, but I don't believe that the amps are different than the earlier model
